12 Claims. (01. 26042) This invention relates to the production of polymeric compounds and to the production from such compounds of threads, fibres, filaments and the like, hereinafter generally referred to as threads.
It is known that epichlorhydrin may be reacted with aliphatic, aromatic or heterocyclic secondary amines to produce non-polymeric products; for example British Patent Specification No. 275,622 describes the reaction of epichlorhydrin and secondary amines to form a-tertiaryaminoepihydrins which are then reacted with bases to form unsymmetrically substituted diaminopropanols.
The specification of application Serial No. 124,944, filed 1 November 1949 describes a process for the production of thermoplastic resins by heating substantially equimolecular proportions of epichlorhydrin and at least one aromatic dihydroxy compound in which the hydroxyl groups are phenolic and the carbon atoms linked to the hydroxyl groups are separated by at least one other carbon atom, together with a quantity of an alkali such that the ratio of the number of molecules of alkali to the number of molecules of the dihydroxy compound is at least 1.0, the heating being continued until a fibre-forming resinous product is obtained.
French Specification No. 933,219 describes the production of resinous products suitable for use as anion-active agents by condensing at least 2 mols of an alpha-chloro, beta, gamma-epoxy compound such as epichlorhydrin with one mol of a polyalkylene polyamine, preferably in the presence of a strong alkali.
The object of the present invention is to produce a novel class of polymeric compounds which are in general suitable for the production of threads.
In accordance with the present invention, a process for the production of polymeric compounds comprises heating together, in substantially equimolecular proportion, epichlorhydrin and a bifunctional compound having as one of its functional groups a secondary amine group and as the other functional group a secondary amine group or a hydroxyl group. The functional groups of these bifunctional compounds are separated by at least 4 carbon atoms, and the compounds contain either a benzene ring or a saturated heterocyclic ring structure containing 5 carbon and one nitrogen atoms. According to the invention, the epichlorhydrin and the bifunctional compound are heated together with an alkali in an amount which is at least substantially the chemical equivalent of the chlorine content of the epichlorhydrin used.
In accordance with further embodiments of the present invention, the bifunctional secondary amino compound as defined is partly replaced, for example by a dihydric phenol as used in application Serial No. 124,944 or by a monohydroxy benzoic acid such as parahydroxy benzoic acid whereby mixed polymeric products are obtained. I
The present invention therefore also includes 1 a process for the production of mixed polymeric products which comprises heating together epichlorhydrin, a bifunctional compound having a' secondary amine group as one of its functional groups and as the other functional group a group chosen from the'class consisting of secondary amine groups and hydroxyl groups, the functional groups being separated by at least four carbon atoms, said compounds containing either a benzene ring or a saturated heterocyclic'ring structure containing five carbon and one nitrogen atoms, an aromatic dihydroxy compound in which the hydroxyl groups are phenolic and the carbon atoms linked to the hydroxyl groups are separated by at least one other carbon atom, and an alkali in an amount which is at least the chemical equivalent of the chlorine content of the epichlorhydrin used, the combined proportions of the said bifunctional compound and the said aromatic dihydroxy compound used being substantially the equimolecular equivalent of the epichlorhydrin used. 7
The invention also includes a process for the production of mixed polymeric products which comprises heating together epichlorhydrin, a monohydroxy benzoic acid, a bifunctional compound having a secondary amine group as one of its functional groups and as the other functional group a group chosen from the class consisting of secondary amine groups and hydroxyl groups the functional groups being separated by rates. .for example by first reacting the epichlorhydrin "with from 50 to 100 per cent of the bifunctional bon and one nitrogen atoms; and an alkali in an amount which is at least the chemical equivalent of the chlorine content of the epichlorhydrin used, the combined proportions of the said bifunctional compound and the monohydroxy benzoimacidused .being substantially the equimolecular equivalent of the epichlorhydrin used.
In making mixed polymeric products according to the invention the bifunctional secondary amino compound as defined preferably forms at least per cent of the mixture which is reacted with the epichlorhydrin. and the; alkali.
Suitable secondary amino bifunctional compounds for use in the present invention are- 4,4- dipiperidyl CH CH; CHECH NH CHCE /NH CHrC: GEE-CH1 para-methylaminophenol and other N-alkylsubstituted amino phenols, and bis-4,4-(N- methylaminophenyl) methane, HsC-HN Suitable dihydric phenols for-use in making mixed polymeric products are 'hydroqui-none,
resorcinol and 3,3 or 1 4,4 'dihydroxy diph'enyls.

Mixed polymeric products may beprepared according to .theinventionrby heating the four-re- V actants. as defined together, preferably under a reflux condenser, until a resinous mixed polymer separates. Two-stage processes may also be ..used. For-example the .bifunctional secondaryamino-compoundas definedmay be used .in one stageandardihydricphenolas definedor a mono- ..hydroxy .benzoicaoid usedin the. other stage;
, thus. 1. molof the dihydric phenol, 2 .mols of epichlorhydrinand. 2. .mole .of alkali may be reacted together in the .ifirststage to form anarcmatic bis-glycidyl etherby the method described by Wernerand Farenhorst -(Receuil .des .Travaux .Ghimique ,de Pays..Bas,.vol..67. (-1948) ,lpages 438 to. r441) .and then. reacting the. ,bis-glycidyl ether withrlmoliof the bifunctional secondary-amino compound toform aresinous mixed polymeric 7 .product.

iinedor with ahydroxy benzoic acid maybe used inpbothi stages.
.Theprocesses according to the invention are preferably effected in the presence of a diluent such .as aqueous alcohol.
The epichlorhydrin may be formedin situ by using alphaor beta-glycerol dichlorhydrin, or a mixture of both, with one molar equivalent of caustic alkali, in place of the epichlorhydrin. In this case, the caustic alkali used to react with the glycerol chlorhydrin is additional to the alkali required to efiect the reaction according to the invention.
The polymersobtained according to the invention are in general thermoplastic products of high =molecular weight which can usually be drawn ormelt-spun to form threads generally capable ofbei-ng cold-drawn.
The-invention is illustrated by the following .iExamples in which the parts are by weight:
i g Example 1 lll'lwparts' (11mm) of epichlorhydrin, a boiling :s'o'lutioniof mar-parts (1 mol) of 4,4, dipiperidyl in 160 parts of ethylalcohol and a cold solution of 4.55 par'ts (1.04 mol) of caustic soda in parts of water were mixed together and heated for 3 hours under a reflux condenser. At the end of i this time a finely-divided precipitate had formed;
the pasty mass was poured into twice its volume of water, filtered and the precipitate was washed three times-with hot water and dried at 100 centigrade.
The polymereobtained had-an intrinsic viscosity in a 1 per cent solution in meta cresol of 0A2-and when heated was capable of being drawn into Example '2 A product consisting of themixed stereoisomers of 1: 4 bis (2 :3 epoxypropoxy) benzene (otherwise known ashydroquinone bis-glycidyl ether) was prepared from 1 mol of hydroquinone, '2'mols of epichlorhydrin and 2 mols of caustic soda by the .heatedunderreflux for 3 hours.

The reaction mixture was diluted with 500 parts of water, brought to the boil and filtered hot to separate the product which was washed twice with boiling water and dried.
The product was an oil-white fibre-forming thermoplastic powder which softened at 200 centigrade. Its intrinsic viscosity in a 1 per cent solution in meta-cresol was 0.41.
